R-16 insulation value from 5 mm of insulation with very thin reflective foil on both sides!
Read that again. FIVE mm of insulation gives R-16 value! R-16 !
5mm equals LESS than a quarter inch! .197" to be more precise.
Whatever small space your insulating, don't make it substantially smaller with THICK foam insulation (or any other thick insulation).
The smaller the space, the more important THIN insulation becomes!

My cousin is using this insulation for a big metal building. Very noticeable difference.
If we had a "Camper Building Materials" category, I would post this there, but I don't see one....
